power details

The old case is compatible with this? (new connector)
Is the Ipower compatible with the 1.2 version, independent powering?

Old cases are for Boss , they dont have the opening of the 1.2 Boss

Ifi power should be fine, Boss 1.2 only needs 150ma

Thank you for your response.

Anyone able to directly compare ‘old’ and ‘new’ Boss cards?

I like these changes! :wink:

Why not use a better DAC chip? To make a pro version.

We are working on it.

Are you working on a project with a 9038q2m chip?
I think I had read that on another thread.

Yes, no other detail is available at this point

Ok thanks.

I am upgrading my headphone setup from a to b.
Now i am looking for a high quality DAC. But on a budget. Got my eyes on a smsl M8.

Now i am running hifiberry Digi+ to an smsl Sanskrit DAC.

The Boss V1.2 sounds great to me. But…

Is it possible to feed the Pi with USB Audio?
Or put on an extra board for optical or/and coaxial inputs?
So i can use the Pi as a dedicated dac with other sources?

You can attach something to the USB and read files from it

You can use a DigiOne for spidif out (top of RPI)

You canot combine a Boss and DigiOne

Thanks for clarification… Allready thought something like this.

I have a tinkerboard on its way and feed it with usb to a dedicated DAC.

It’s a bit offtopic but it would make a nice upgrade if you guys came up with something to add extra inputs!
I don’t mind put it on my stack of Pi, Isolator and Boss :smiley:

Hi friends,

i will compare the boss DAC with the boss DAC V 1.2. next week, so stay tuned :wink:

Which is a better sounding combination?

  1. RPI3 + Boss 1.2 DAC, OR
  2. Tinker board + Boss 1.2 DAC

Got my Boss 1.2 DAC today.

I replaced it and played my favourite audiophile quality flac & wav files thru it. With the jumper on, I connected the IFI power to the dac.

Wow! What a wonderfully clear and musical sound.

ALLO, you have done a great job on this DAC. Appreciated !!
